In October of the year 2174 of the New Calendar, Val City was attacked by the Demon Clan and was completely destroyed, with only a few people who happened to be outside the city escaping the disaster.
Under the efforts of Sword Saint Jia Pael, professors from the Magic Association, local adventurers, and nobles, members of the Demon Clan who slaughtered innocent people were all eliminated.
Investigations into the purpose, method, and timing of the Demon Clan's invasion of Val City were swiftly underway. Although the frequency of Demon Clan attacks had been intensifying over the years, there had never been an incident where a city so far from the border like Val was completely slain by the Demon Clan.
